PASTING AND ourrrne'lvrnonrnn 2 Application filed January 30, 1922.Serial No. 532,876.:

Toallwhomc't may concern: j

- Be it known that 1,:JOSEPH OPPMA'N', a citizen of the United States,residing at @onnellsville, in the county ofFayette and State ofPennsylvania, have invented certain new and useful Improvements inPasting and Cutting Machines, of which the following is a specification.

This invention relates to apparatus for 1 simultaneously applying pasteto rolls of paper and severing the same into strips of uniform widths,and has for one of its objects to simplify and improve the constructionand increase the efliciency and utility of devices of this character. I

Another'object of the invention is to provide a device 'of thischaracter which may be adapted to rolls of paper of varying widths,,andto apply-paste uniformly to 2 the whole web and sever the same intostrips of varying widths.

' .Another object of the invention is to provide a device of thischaracter having means whereby the flow of paste to the paper may beaccurately controlled. I p I With these and other objects in view theinvention consists in certain'novel features of construction ashereinafter shown and.

described and then specifically pointed out in the claim, and in thedrawings illustrative of thevprefered embodiment'of the invention 1 VFigure 1 is a plan view: of the improved apparatus with the roll ofpaper in position. 1 Fig. '2 is a transverse section on the line22of-Fig.1. V 'f'. #Fig. 3 is a front elevation with the" roll of paperremoved. 40 Fig. 4 is a rear elevation with a part broken away. 1 i Fig.5 is a sectional detail illustrating the construction of the troughmember of the apparatus;

p the cutting wheelholder. t

Fig. 7 is an enlarged sectional detail illustrating the manner ofsupporting the drum for rotation. p

Fig. 8 is an enlarged sectional detail of Fig. 6 is an enlargedsectional detail of ing wall paper into webs of uniform widths,

the adjustingv device for the paste flow con- Y but may be readilyadapted to applying paste and serving webs ofpaper of any width andlength.--

The improved apparatus comprises asupporting structure including abottom memher 10 and'end member 11, ,of relatively heavy material,preferably-of wood. Supported between the end'members 11 isa troughpreferably of sheet metal 12,.and having one side about in line with thecenter of the trough,.as shown at 13',"and the other side extendingupwardly as shown-at. 14:.

The portions 12, 15 and 14 are embedded I i at their ends in channelswithin the end.

members 11,-as shown in Fig. 5', to insure paste tight joints betweenthe parts.

Extending between the endmembers 11 V is an L-shaped member 15,preferably of sheet metal, and coacting with the upwardly extending side14 of the trough to form a tank or reservoir for paste. V

The side wall 14: of thetrough also forms one wall of the tank, thelatter underlying a portion ofthe trough as indicated at 16. A pluralityoforifices 17 are formed in the bottom of the trough and providecommunie q Mounted for rotation in'the trough .12.

is a drum comprising a cylindrical-body 20 and closed ends, one .ofwhich is shown at 21 in Fig. '7, and disposed in theend members .11 areinternally threaded sleeves,

one of which is shown at 22, to receive threaded-pins 23" which engageby their inner unthreaded'xends in wear sleeves 21 in the heads 21 ofthe drum;

By this means the drum is mounted for, rotation on the end members 11and is therefore rotative in the trough.- The b arrel or body 20 of thedrum is conand be spread uniformly over the barrel of the drum as thelatter is rotated, as.

hereafter explained.

Bearing upon the curved lower part-of the wall of the trough which alsoforms the adjacent wall of the tank, is a correspondingly curved cut-01fplate 25 whose lower portion serves to close the orifices 17 when in itslower position and to open the orifices when in its higher position, andpartially close the orifices when in intermediate position. By thismeans the 'flow of paste from the tank to the thin space betweenthetrough and drum can be controlled by adjusting the plate 25.

Means are provided for adjusting the position of the member 25,consisting in a stud 26 rotative in the wall 14 of the trough and tankand with an eccentric 27 at one end within thetank and a squared portion28 and a threaded portion '29 externally of the u all 14.

Engaging on the squared portion 28 is milled set collar. 30, andengaging the threaded portion of the stud is a milled clamp nut 31.

Bearing around the eccentric'27 is a strap device 32, and extending fromthe strap is Extending between the end members 11 is a guide roller'35havingjourna'ls like those employed for mounting the drum 20-21, andincluding milled clamp members 36 like the members 23. 7

The roller 35 is preferably located above the center of the drum 20-21,as shown in Fig. 2.

Formed in the inner or confronting faces 7 of the end members llarevertical guideways 37 to receive the journals '38 of a bear j ing roller39. a r

. .Formedin the confronting faces of the end members 11 are. horizontalguideways 40 to receive the ends of a rod 41 designed to support arollof paper indicated at 42. The rod is held from'displacement by hooks41 i as shown.

The end of the web 43 of paper is passed between the barrel 20 of thedrum and thej bearing roller 39: and thence between the barrel 20 oftherdrurn and the guide roller I 35 and'thence drawn *upwardly,'fthe"pull: g

:thedrum to be rotated and carry a thin film of pastewithitandapply-it-uniformlyupon ing upwardly of the web of paper causingthe paper as it is drawn over the drum and held in contact therewith'bythe gravity of bearing roller-39.

By this means the requisite amount of paste is uniformly and evenlyapplied to the paper as it is drawn upwardly, and the paper held incontact with the drum by the 7 weight of the bearing roller 39 withsuflicient tension to insure the proper action. 1

By adjusting the member 25, as 'be'forede scribed, the ambunt of thepaste which" passes into the confined space between the trough 12 anddrum'20 and thereby carried up against the paper '43, can be accuratelygaged'. V r Extending between the end members 11 is a rod 44, andslidably and rotati'vely engaging the rod is a holdingmember 45 :havinga split bearing 46 providedwith 'a c'lam'p I bolt 47 to enable themember 45 to be clamped upon the rodin adjusted position.

The mem'ber45 is; formed with' an upwardly opening recess 48 -,'-and'piv'oted at '49 in the recess is an arm 50 having a cutting wheel "51pivoted in one end. Formed upon the member 45 is an arching "support52'to receive an adjusting screw 53, to control the position of themember 45 and the cutting wheel carried thereby; Y

A compression spring 54 is-disposedinjthe recesses 48,'andyieldably'supportsithere 1 cess engaging end of the member 50.;

The rod 44 will be so 'disposed' t'ha't-"the cutting wheel 51' bearsagainst the guide roller '35, and thus seve'rs the paper '43 as thelatter is drawn upwardly.

The severing member being adjustable longitudinally of the rod 44, itwill be obvious that any required width of paperniay be severed, and byproviding a plurality of the severing devices the paper may besevered ina corresponding number of strips of any required width, or varyingwidths.

The improved apparatus is simple in construction, can be inexpensively Emanufac-* tured of any required size and of any suitable material, andoperates effectuallyfor the purpose described. v I

The preferred embodiment of the invention is disclosed in thedrawings-"and set forth in the specification, but it will be understoodthat modifications within tl'ie scope of the claimed invention-maybemade in the construction without departing from the principle of theinvention or sacrificing any of its advantages;
